Patent Oflice under date of August 9, 1919,.

' Serial No. 316,374.

The invention relates to an improved machine for producing roofing products and has for its object to produce embossed paper or felt roofing material which has been saturated or impregnated with asphaltum or other tbituminous substance and which may or may not have a granular surfacing. It also concerns the hollow pocket formed beneath the embossed part which may be filled to make the lower side of the roofing a smooth surface. I

Another important object of the invention is to provide a machine for producing embossed roofing material which has the appearance of shingles, tile or the like and producing them in such a way that there is furnished a mode of laying these roofing strips which is less diflicult than the flat roofing strips and can be more permanently affixed due to the lower edge of the strips abutting upon the upper shoulders of the embossed portions of the strips below, making a more unified combinatifii or assembly.

The machine herein disclosed consists of apparatus for producing roofingcomprising pliable units out from a sheet in whichare impressed or stamped raised portions which have .the concave indentures formed on the under side of the sheet filled with an adhesi ve substance such as asphalt or other bitumens. The hardening of the adhesive substance in the indenture prevents the fiat-tening of the raised portions which appears on the upper surface of the shingle units and assists materially in laying the shingle. The asphalt which is pressed on the surface of the sheet produces a distinct desi n which may be made to resemble a. shing e design of any type.

Fig. 17 is detail view in cross section of of the cutting rolls for material produced as illustrated 1n Figs. 4 and 5.

Referring to the drawings, in Fig. 1, the roofing material 1 is shown with the embossed portions 4 produced thereon. These raised or embossed patterns are made when the roofing material passes between the embossing rolls 5 and 10 in Fig. 4. The upper pressure roll 5 has upon its surface a series of recesses 6 systematically arranged so as to register with similarly shaped bosses 9, upon the lower bed roll 10. These rolls are revolved by means of any suitable power, not shown, in the direction shown by the arrows in Fig. 5.

In Fig. 5, a section of roofing is shown in the process of being embossed. A cross section of, the embossed portion is shown at 11.

In Fig. 9,.the recesses 13 and bosses 14 are longitudinally arranged upon the pressure roll 15 and bed roll l7-so as to produce a larger pattern as shown in F ig. 6. The roofing material in Fig. 6 is out along the dotted lines, making strips with projections 18 and notches 19 along the sides of each strip next to the top edge. These projections and notches are fitted in laying the material asshown in Fig. 13.

In Fig. 10, the roofing material is indicated between the rolls just after the part has received the stamp of the embossing ies.

Fig. 11 is a section of laid roofing, the arrangement of the strips the same as in Fig.

13,, except that these strips have not the projections and notches near the top of each strip used to fit them together as shown in Fig. 13. Each strip in both Fig. 11 and Fig. 13 overlaps the one below it and has its lower edge 21 abutted'upon the upper shoulders 21 of the embossed portions 4 of the strip below, thus making a very rigid assembly. A,

In Fig. 15 is an embossed granular, surfaced roofing strip 22. The dark shaded portions 23 are caused by the bosses 9 on the bed roll 10 shown inFig. 4, forcing the asphaltic substance through the roofing material, giving the top surface on the embossed parts a darker color than the surrounding material.

In Fig. 16, the pocket 24 under the embossed parts of the strip is shown in cross section filled with material (preferably asphaltic) making a smooth under surface on the strip.

In Fig. 17, the chain of operations is shown in producing the embossed roofing strips. The material is directed through the'apparatus by power, not shown. Only that part important to the understanding of my invention is represented. From a receptacle 25, the material receives a coating of adhesive substance 25, preferably asbetween two phaltic, then passes between the guide rolls 26 and 27. It is then surfaced with a granular mixture from a hopper 28. From there the roofing material is led over a series of cooling rolls 28, 28, 28, 28 and 28, and uide rolls 29 and 30 to the embossing rol s 15 and 17 of the character shown in Figs. 9 and 10.

The lower bed roll 17 having the raised bosses 14 uponvits periphery turns in the direction which the material is traveling (indicated by the arrows) and being partly immersed in a tank 31, containing asphaltum or like substance, takes up a small quantity of this substance in revolving which it rolls onto the under side of the roofing 'materiail.

Another bed roll 32 over which the roofing material passes, gathers-the asphaltic substance at 33, spreads it over the under surface of the material and fills the hollow pockets 24 formed by the embossing dies 13 and 14. This makes the bottom of the material a smooth surface.

A scraper 35 cleans the roll 32, removing all excess filler substance that sticks to the roll, causing it to drop back into the reservoir 31.

The roofing material then passes over the bed roll 36 which is peripherally grooved to accommodate the embossed portions 4 as shown by dotted line 37, and rotates in dusting box 36 which furnishes a non-adhesive coat to the underside of the roofing sheet. The roofingmaterial proce ds over the cooling rolls 38 and 38*, the lat r being similarly groovedas roll 36, it is then conducted onto guide table 39, (Fig. 17) by bed rolls 38". In Fig. 17, a flexible endless conveyer belt 40 travelling over rolls 40 has fixed upon its surface a series of slats 40", so arranged on the belt that the slats take up behind the raised embossed portions and being timed with the severing rolls 41 In 18, the roofing sheet is guided between the several rolls 47 and 50 by a similar mechanism to that shown in Fig. 17?. The bed roll 47 is recessed at 48 to receive cutting edges 49 mounted longitudinally of cutting roll 50 whereby the roofing material is severed transversely as indicated by dotted lines in Fig. 1. If it is desired to have no granular facing upon theroofingv sheet, the

ing mechanism for cutting the sheet into suitable lengths.

2. In an apparatus of the character described, the combination with means for feeding roofing material of embossing rolls functioning therewith to impress predetermined areas of the sheet into raised embossments means for filling the depressed portions formed beneath the embossed portions.

3. In an apparatus of the class described, the combination with means .for feeding roofing material, of embossing rolls func-- tioning therewith to impress predetermined portions of the sheet into raised embossments, means for applying a filling substance to the depressions produced on the reverse side of the sheet by the embossed portions. a

4. In an apparatus of the class described, the combination with means for feeding roofing material, of embossing rolls functioning therewith to impress the sheet into predetermined designs'by embossing selected portions of the sheet, mechanism for cutting the material longitudinally and-transversely into units;

5. In an apparatus of the character described, the combination with means forfeeding roofing material, of embossing rolls functioning therewith to impress embossments into predetermined portions of the sheet, means for'applying an adhesive substance to the depressed portions produced on the reverse side of the sheet by the embossments, a pressure roll rescessed to accommodate the embossed pattern and having onits periphery a series ofequi-spaced cutting edges arranged to cut the roofing material into units of a predeterminedconfiguration.

6. In an apparatus of the class described the combination with means for feeding a roofing sheet, of embossing rolls functioning therewith and deforming the sheet in predetermined areas to form embossments, means for applying an adhesive substance and a granular non-adhesive material upon the sheet, means for applying an adhesive substance to the depressions in the reverse side of the roofing sheet produced by the embossments, severing mechanism for cutting the material into shingle strips.

7. In an apparatus of the class described, the combination with means for feeding roofing material, of an upper pressure roll having a series of recesses upon lts pe-v riphery, a lower bed roll provided with bosses which register with depressions in the lower pressure roll, said roll cooperating to impress embossments into predetermined areas of the sheet, a severing mechanism for cutting the material into shingle strips.
